ASPECIE"IGACLION forming part of Letters Patent No. 758,386, dated April 26, 1904.

Application filed .Tune 2U, 1903. A Serial No. 162,322. (No model.)

To @ZZ whom. zit party concern: B e it known that I, GEORGE H, RICKE, a citi- Zen of the United States, residing at the city of Cincinnati, in the countyv of Hamilton and State of Ohio, have invented certain 'new and useful Improvements in Bung-Bushings, of which the following is a specification.

The object of my'inventionis to produce a cheap, simple, and efficient bushing for bungs to be used in beer and other packages for holding liquids. 1

A further object is to produce a bushing which will prevent the bung-stave from cracking or splitting, the bung-stave being the stave selectedl to carry the bung and bungbushing. To accomplish this object, I provide a bushing with an upper and lower screwthread, a space or cut-away portion without screw-thread being left between the two sets course every time the hoops are redriven, and Y this is a frequent occurrence during the life of the keg or barrel, the staves are more tightly compressed, as isalso the head of the keg. Consequently and naturally the keg becomes smaller. The iron bushing of course remains the same size, and the bung-stave being compressed along with its companions assumes a more marked degree of curvature as the hoops are forced down more tightly on the bilge and quarter of the keg. The screwthreads of the bushing press outward against the wood of the stave surrounding the bushing. In this way the stave cracks or splits in the center or outside, producing a leak in time, this necessitating the replacing of a new bungstave. There is no place for the wood-around the bushing to go. It must give with the bushing, and thus is cracked and broken. My new bung-bushing overcomes these defects. I use only about two-thirds of the .new bushing.

amount of screw-threads and leave a space at the center between the bushing and the stave edge, so that when the hoops are redriven I have less pressure against thebushing, and the space allows the wood vto adjust itself to the new position around the bushing, preventing cracking and breaking. This space in the bushing also helps to strengthen the stave at the center, Where strength is necessary when the keg is being pitched. The immenseheat of the pitching-machine is not communicated directly against the wood, as the bushing does notrtouch it at this place. Great pressure is used in screwing these bushings home, and in this manner the bung-stave is often cracked. I also prevent this, as I cut down the degree ofl 4friction between the bushing and the wood when my bushing is inserted.

In the' accompanying drawings, forming part of this specilication, Figure l is a top View of my bushing in the bung-stave, the stave being broken away. Fig. 2 is a central longitudinal section taken at the line X X of Fig.l, and Fig. 3 a view in elevation of my The dotted lines in Fig. 2 show the varying degrees of curvature assumed by the stave incident to the redriving of the hoops.

In the drawings, a represents the bung-stave, b the bung-hole, and c the bung-bushing. The bung-bushing is an annulus or ring widest at 'the top, where it is surmounted by a flange al, and tapering toward the bottom; smooth on the inside. At its periphery the bushing c is provided with a series of upper screw-threads e and a series of lower screw-threads g. These screw-threadsv encircle its entire periphery.

Between these two sets of screw-threads e and marked 7L. This space may be as deep asl desired, and its extent may be varied. This peculiar formation of the bush prevents the stave from cracking when the hoops are redriven, as before described, allowing the wood to give somewhat, and thus adjust itself. y

,If desired. I may encircle the bottom of the liange l with a rib or tongue to assist in tightening the bush in the stave.

so that said end of the band will be permanently secured to the plate. This will cause the clamping-plate to be secured to the end of the band without danger of detachment therefrom, and when itis desired to bind the staves of the cask in position the band is placed around the same and the opposite or free end thereof-in the present instance the end Z2-is passed through the slot 12 of the plate 5 and beneath the inwardly-extending teeth or tongues 14 14, cut from the body of the plate in a manner similar to the teeth 13 13, and by the blow of a hammer, mallet, or the like the aforesaid teeth 14 14 may be driven inward through the end of the band, the latter being formed of material which is preferably softer than the material from which the plate of the clamp is formed, so that the teeth 14 14 of the plate may penetrate said band Without danger of bending or breaking.

In order to prevent the teeth 13 13 and 14 14 from entering the sides of the cask or engaging therewith in such manner as to prevent the band from being moved downward upon the cask-body to tighten the same, I provide a plate 16, which for the purpose of conveniencev I shall designate as a bearingplate, and this plate is formed with flanges 17 17, designed to fit over the longitudinal portions of the main plate of the clamp, the end portions of the clamp bearing against the shoulders 9 9 and 1() l() of said main plate.

The aforesaid supplemental or bearing plate 16 is provided with an approximately U- shapedcut-away portion 18, "and the end of the extending end of the band after passing through the slot in the plate lies next to the cask in the slot portion 18, as clearly seen in Figs. 2 and 3.

In Figs. 6 and 7 I have shown a slightlymodifed form of tie-clamp, the latter being especially designed for use in securing tiebands of bales of cottonV and the like. In this instance the teeth 19 19 of the plate 7, which are designed to permanently secure the clamping-plate to the band, are turned outwardly, while the opposite set of band-engaging teeth 2O 20 are approximately triangular in shape, extend inwardly, and are designed to be driven through the opposite end of the band in such manner that after passing therethrough said teeth will penetrate the cottonbale and hold the ends of the bands against separation.

It will be observed thatI have provided an exceedingly simple device for accomplishing the securing of a hoop or band to a cask, bucket, or the like, and one which will hold the staves or parts of the same securely and firmly, while at the same time the size of the band may be adjusted to vessels of varying circumference by pulling the free end of the band through the slot in the plate until the band is sufficiently tight, when the securingteeth may be bent to rigidly hold the ends of the hoop or band.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a band, of a device for connecting the ends thereof, said device comprising a plate having enlarged end portions, said end portions being each provided with a slot designed to permit the passage of the ends of the band, and teeth formed on the body of the plate and adapted to penetrate the ends 'of the band passing through said slots, the construction being such that said ends may be firmly connected, and a bearing-plate adapted to be interposed between the band and a cask or the like to which the band is secured, substantially as set forth.

2. rI`he combination with a band, of a device for connecting the ends thereof to form a hoop, said device comprising a plate having slots formed transversely of the end portions thereof to permit the passage therethrough of the free ends of the band, a plurality of teeth arranged adjacent to each of said slots and designed to penetrate the material of the ends of the band for securing the same, and. a bearing-plate adapted to engage with the plate and slide over the portions of the band engaged by the teeth, substantially as set forth.

3. A device ofthe class described, comprising a plate having enlarged end portions, a slot formed ,transversely of said end portions, said slot being designed to permit the passage of the end of a band, teeth formed from the material of the plate and adapted to penetrate the material of the ends of the band for connecting said ends with the plate, and a bearing-plate formed with flanges adapted to engage with and Jt over the relatively narrow longitudinal edge portions of the main plate and to cover the portions of the teeth extending through the band, substantially as set forth.

4. The combination with a cask, bale, or the like, of an adjustable clamping-hoop therefor, said hoop comprising a band portion, a clamping-plate provided with a plurality of teeth designed to connect the ends of the band portion; and a bearing-plate adapted to be interposed intermediate the clamping-plate and the cask. substantially as set forth.'

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.

WILLIAM P. RICE.
